Abstract
The utility model discloses a short circuit-proof power switch, which comprises a base, terminals fixed on the base and connected with electric wires, a button arranged at the notch of the base, a rocker connection assembly connected onto the button, a connection piece corresponding to the rocker connection assembly and used for being communicated with the circuit, and an insulation piece fixed in a rotating mode inside the base and located between the connection assembly and the connection piece. According to the short circuit-proof power switch, water infiltration can be detected, contact pieces are blocked via an insulation rod so as to cut off the circuit in the case of water infiltration, large-scale accidents such as electric leakage and fire caused by short circuit can be avoided, safety use of the power switch can be ensured, the cost is low, and the effects are good.
Description
Technical field
A kind of electric equipment, particularly a kind of mains switch.
Background technology
Mains switch of the prior art all can not waterproof, in infiltrating mains switch, water is easily short-circuited, and electric leakage or breaking out of fire etc., the security performance of mains switch cannot ensure, prior art is unresolved such problem also.
Utility model content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide one whether can detect water leaking-in, if water leaking-in just cuts off circuit, avoids short circuit that the Accident of Large-scales such as electric leakage or fire occur, and guarantees the fail safe that mains switch uses.
In order to realize above-mentioned target, the utility model adopts following technical scheme:
The mains switch of anti-short circuit, comprise: pedestal, be fixed on pedestal and connect the terminal of electric wire, be placed in the button of pedestal indentation, there, be connected in the seesaw coupling assembling of button, corresponding to seesaw coupling assembling and for the connector of connection circuit, rotate the insulating part being fixed in pedestal and between coupling assembling and connector.
The mains switch of aforesaid anti-short circuit, seesaw coupling assembling composition has: one end is connected in the spring of button, the first contact chip of the linking springs other end.
The mains switch of aforesaid anti-short circuit, connector is the second contact chip corresponding to the first contact chip.
The mains switch of aforesaid anti-short circuit, insulating part is insulating bar.
The mains switch of aforesaid anti-short circuit, is provided with rotating shaft between pedestal and insulating part.
The mains switch of aforesaid anti-short circuit, also comprises: be connected in rotating shaft and be placed in the humidity sensor in pedestal.
Usefulness of the present utility model is: the utility model provides one whether can detect water leaking-in, thereby if just intercepting out contact chip by insulating bar, water leaking-in cuts off circuit, avoid short circuit that the Accident of Large-scales such as electric leakage or fire occur, guarantee the fail safe that mains switch uses, and cost is low, effective.
Brief description of the drawings
Fig. 1 is the sectional view of a kind of embodiment of the present utility model;
The implication of Reference numeral in figure:
1 pedestal, 2 terminals, 3 insulating bars, 4 humidity sensors, 5 buttons, 6 springs, 7 first contact chips, 8 second contact chips, 9 rotating shafts.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done to concrete introduction.
The mains switch of anti-short circuit, comprise: pedestal 1, be fixed on pedestal 1 and connect the terminal 2 of electric wire, be placed in the button 5 of pedestal 1 indentation, there, be connected in the seesaw coupling assembling of button 5, corresponding to seesaw coupling assembling and for the connector of connection circuit, rotate the insulating part being fixed in pedestal 1 and between coupling assembling and connector.
Seesaw coupling assembling composition has: one end is connected in the spring 6 of button 5, the first contact chip 7 of linking springs 6 other ends.Preferred as one, connector is the second contact chip 8 corresponding to the first contact chip 7; Insulating part is insulating bar 3; Between pedestal 1 and insulating part, be provided with rotating shaft 9.Insulating bar 3 moves to the connection of open circuit between the first contact chip 7 and the second contact chip 8, thereby realizes power-off.
The mains switch of anti-short circuit, also comprises: be connected in rotating shaft 9 and be placed in the humidity sensor 4 in pedestal 1.
Humidity sensor 4 is responded to humidity and is arrived set point, and controller control rotating shaft 9 is rotated, and turns to the connection of open circuit between the first contact chip 7 and the second contact chip 8, thereby realizes power-off; When humidity sensor 4 senses that humidity is under set point, controller control rotating shaft 9 is rotated, and the first contact chip 7 contacts again with the second contact chip 8, connecting circuit.
Whether the one that provides the utility model can detect water leaking-in, if thereby water leaking-in is just intercepted and is opened contact chip and cut off circuit by insulating bar 3, and avoid short circuit that the Accident of Large-scales such as electric leakage or fire occur, guarantee the fail safe that mains switch uses, and cost is low, effective.
More than show and described general principle of the present utility model, principal character and advantage.The technical staff of the industry should understand, and above-described embodiment does not limit the utility model in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection range of the present utility model
